We may have an opportunity to adopt a 3 year old which is the same (herding) breed as our current DDog. It would be an international adoption so no chance for introductions at the rescue.
All the online advice is to introduce the dogs on a walk on neutral territory. However, DDog is leash reactive so I think this would go badly. He isn't aggressive and has been with other dogs offload in multiple settings (including daycare) with no problems. Would love some expert tips on how to manage this dynamic - we can separate in the house using a baby gate and have a very secure yard. I know we will need to set up separate sleeping and eating areas and to put all toys away for a while.
